Good Morning from Sunny Athens!

So as I started my car this morning (23i) I heard a whinning from the AC. it only occurs when I turn the ac on and off and only for a second. Its like something rubs plastic to plastic, I really don't know how to described it so I uploaded the below video.

When the music is on you cannot hear it. The ac works fine, sound occurs only when you switch on/off.

It could have been there before and just noticed it now, I only own the car for a month!!!


any advice or thoughts will be highly appreciated!!
 
Could be a blower motor bearing starting to go. Could be something sucked in to the system and rubbing on a fan.
 
Quick update,

Passed by an car ac shop and the confirmed ac is working perfectly. I worked the ac on all modes and all in good order. Aas usual, when at the shop the sound stopped.

The ac guy told me to just go and if it comes back to go check it again. Maybe when I ran the ac on different modes something unstuck or got warmed up and stopped.

I don't think I should Bother anymore.

thoughts any one?
 
i will tell you a sad story.. once upon a time i had a lexus soarer 32, and i was in somewhere deep in europe and my aircon started to screech, this concerned me greatly as it was the height of summer i had already done spain at this point and it couldnt cope., anyway a screech started and of course stopped when i turned the ac off. sooo. i opened the windows and cooked for the rest of my holiday. on my return i took it a man, who said, i cant do anything with it as its the old gas, it will have to be converted, it cost a 1000 almost..
so i picked it up and the noise started again.. i said whats goin on ?? he said it aint thr ac mate.. thats fine.. so i took it away 1000 quid lighter and still got the squeal. i tracked it down to a pulley bearing - it cost 4 quid to replace..

soo.. pulley bearing, or belt or compressor ..

oh and yes.. my ac failed on my motorhome, nothing fitted.. turns out it was aftermarket fitter, the compressor came from a combined harvester the condensor from a range rover and dryer from a john deer tractor. :headbang:

£1000 bill for unnecessary work? I’d have lost my cool even if the ac was working properly :cry:

So after googling a bit there might be a problem with my actuator which is located behind dash somewhere.

Did anyone face this issue?

From what I 've read the whole dash has to be removed to get to the area! The actuator is cheap but someone said that BMW asked for 1500usd to just remove and diagnose!


hope this is not the case.
